BINDER-FRAME.

Patented Sept. 1 7, 1912.

To all whom it may concern: 7 Be it known that I, FRED L. MANNY, of thecity of Benton Harbor, county of Berrien, and State of Michigan, .haveinvented certain new and useful Improvements in Binder-Frames; and I doherebyv declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings. My inventionrelates to that class of bin'ders in which all the binding parts areincluded between two clamping bars and resides in the various noveldevices and combinations of the same herein illustrated and describedand pointed out with more particularity in theclaims appended hereto.

In the drawings, Figure 1 represents a front elevation of my binderframe in an unlocked or open position. Fig. 2 repre sents a sectionalplan view taken through Fig. 1 at the'line2'2. Fig. 3 represents a frontelevation of my binder frame in a locked or closed position. Fig. 4 is asectional view of Fi 3 taken through the line 4-4 of Fig. 3. igs. 5 and6 represent de tails of the locking mechanism ofmy binder frame.-

More particularly described, A and'B represent the binding members ,ofmy binder andconsist of a and b the binder bars aand b the back flangesof the same, and a and b tubular sockets secured to the bars a and b -attheir juncture withthe back flanges a and b, and secui'ed oppositely toeach other. These parts a, a and b b" and b of the binder members A andB are preferably made of one castingor if of more than one piece aresecured rigidly together. The covers P and P are hinged respectively tothe members A and B.

0. represents the middle back of my binder and consists of a strip ofrigid material lying back of and parallel with. the said binding membersA and B, and overlapping the flanges a and b. In the proces of openingand closing or expanding and contracting the parts of my binder, themembers A and B are designed to move from and toward each other, therebyalter 5o nately increasing and diminishing the distance between theflanges a and b. Inasmuch as the flanges a' and bi together with theback C are intended to cover and rotect theback ends of the leaves, thelihck 0 must be so constructed that when the flanges a and b are drawnapart in the expansion of the device, the back C will at all times coverthe space between the said flanges, thereby effectually protecting theback end of the leaves. I provide, therefore, means whereby the back Cis held at all times in,the same relative position to the members A andB. This means I describe as follows :-+A series of disks or pitmencranks D D, I secure ivotally to the inner face of the back C. To thesedisks or pitmen cranks D D, I secure ivotally one end of the pitmen d d,the ot 1er end of which are secured by like pivotal engagement to theinner, face of the flange a. Opposed to the pitmen (Z cl, I also securepivotally to the cranks D D, one endof the pitmen d d, and'the other endofthem also pivotally to the inner. face of the flange 6. In'theexansion and contraction of the binder, see

igs. 1 and 2 of-the drawing, the flanges a: and 6 move toward and fromeach other and, carryin with them the pitmen d and d, the cran s DD arecaused to rotate. The pitmen d and d operating in exact relation witheachoth-er, the pivotal connection of the cranks D D with the back areheld in a fixed position thereby retaining the back C in its middleposition as designed.

As it is desirable to insure the members A and B' in operation to movetoward and from each other uniformly throughout their length,I providemeans for effecting this end: The cranks I) D and their accompanyingpitmen d and d forming respec t-ively connections between the flanges aand 5' at different oints, I secure the cranks D D to ether by theparallel connecting rods d ivotally connected at their ends to thecranlEs D D respectively. These connecting rods d d insure exactrelation in the rotation of the cranks D D and through them maintain thesame relation between the binder members A and B. They also act as astop to prevent the rotation of the cranks D D and the consequentseparationof the members A and B fa'rther'than is desirable. Theconnecting rods d al lying parallel to each other and attachedto thesame face of the cranks D D come into. contact with each other laterallyat the point of greatest expansion of the binder frame as shown inFig. 1. This contact acts to check the expansion of the binder frame.

I provide spring posts in my device as follows: Tothe inner face oftheback C and opposite the sockets a b of the'members Aand B, I secureclamps c 0. Within the clamps c c I secure tubes 0 c engaging at theiropposite ends the sockets a a and b b respectively. These tubes 0 c areof such size and length that in the operation of the binder they willtelescope into the said. sockets a b and at no point in the expansionof'the binder will they disengage from said sockets. Within the saidtubes 0' 0' and the engaging sockets a a and b 71 I place expansionsprings 0 c which force the members A and B. apart when released from alocked position.

7 The construction of the binding posts in my device is inconsequentialso far as it relates to the style and shape of them. Any desirable shapeand any desirable style of extensible post may be used. I prefer,however, to use the telescoping posts E E E E. These posts I intend tobe attached either to the respective, binding bars a Z) or to the metalstrip a 6 These metal strips a b are removably attached to the innerface of the said bars a b by means of screws a 6 The screws 6 are shownat Fig. 2 and the i screws a are not shown but attach the strip a to thebar a in like manner as b is shown to be attached to b at Fig. 2. Byattaching the posts E E E E to these metal strips a 11 the posts may bereadily removed from the binder and a different style or a differentnumber of binder posts be inserted in their stead. This form ofattaching the posts I prefer to attaching theni direct to the binderbars a Z). I also provide a post F which is rectangular in cross'sectionand is construct ed of two dovetailing sections attached respectively tothe strips a 6 having sliding engagement with each other as shown atFig. 4, and if, for the purpose of more se-'- cure ahnement of theleaves, some square with the flange b by an axis 9 g which is secured atone end to the flange b and at the other end to the plate 9 which, platecovers the pawls g g. and is secured at itsends to the plate 6 by meansof screws 9". The pawls g g are held normally in contact with theratchet g g by means of the springs 9 The outer ends of the pawls g 9have engagement through suitable perforations in cranks attached to saidbinder back and having operative engagement with the binder members,extenslble posts, and spring carrying tubes attached to said binder backand engaging at their respective ends with sockets attached to saidbinder members, of a lock consisting of a two faced rack attached to oneof said members and pawls rotatably attached to the other of said bindermembers and adapted respectively to engage the faces of the said rack.

2. In a binder frame, the combination with bindermembers, a binder back,pitmen cranks attached to said binder back and having operativeengagement with the binder members, and extensible posts, of a lockconstituting a two faced rack consisting of a U shaped piece ratchetedon its inner face and attached to one of said binder members, andv pawlsrotatably attached to the other of said binder members and havingengagement with the said ratcheted faces respectively.

3. In a binder frame, the combination with binder members, a binderback, spring carrying tubes attached to said binder back and-havingtelescoping engagement at their respective ends with sockets attached tothe said binder members, automatic means for maintaining slidingengagement between the said binder back and the said binder members, andextensible posts, of a lock consisting of a multiple faced rack attachedto one of said binder members, a corresponding multiple of pawlsrotatably attached to axes held between the other of said binder membersand a supporting plate also attached to said other binder member, saidpawls adapted to engage said multiple faced rack.

4. In a binder frame, the combination with binder members, a binderback, pitmen cranks attached to said binder back and having operativeengagement'with said binder members, extensible posts, and. springcarryin g tubes attached to said binder back and having telescopingengagement at their respective ends with sockets attached to said bindermembers, of a lock consisting of a U shapedpiece provided with ratchetson the other binder member, said pawls being inngr face thereof attachedto one 515 saild adapted to engagevsaid ratchets.

1n er mem ers, an sprin actuate paw s rotatably secured to axes which intheir FRED MANNY turn are secured at one end to the ,other of Witnesses:said binder members and at the other end to WILLETT H. CORNWELL, a plateattached to and projecting from said INEZ BERGSTROM.
